TRANSONl-LIFTER.

SPECIFICATION forming part of Letters Patent No. 632,326, datedSeptember 5, 1899.

Application filed March 3l, 1899.

To all whom. t may concern,.-

Be it known that we, JOSEPH SIEWERT and MICHAEL WIsNIEwsKI, citizens ofthe United States, residing at Chicago, Illinois, have invented certainnew and useful Improvements in Transom-Lifters, of which the followingis a specification.

The object of our invention is tov provide a simple, economical, andefficient transomlifter; and the invention consists in the features,combinations, and details of construction hereinafter described andclaimed.

In the accompanying drawings, Figure lis a front elevation of a transomsupplied with our improvements; Fig. 2, a side elevation of the same,shown partly in section, with the transom in its closed position; Fig.3, a similar View showing the transom in a partiallyopen condition; andFig. 4, a sectional elevation of a portion of the mechanism, taken onthe line 4 of Fig. 1, looking in the direction of the arrow.

In'the art to which this invention relates it is well known thatordinarily transoms are frame, so that they turn on pivots, and areopened bymeans of lifting mechanism of various constructions. There areobjections to this class of transoms and their lifting apparatus whenused with large and heavy transoms, such as are used over the doors ofmercantile establishments and stores, in that the entire weight of thedoor is taken upon two small pivots and the transom swings inside aswell as outside.

The principal object of our invention, therefore, is to remove any ofthese objections which are found in connection with transoms of thislarge type and provide sustaining and lifting mechanism which will holdthe transom in the desired positions and which is economical toconstruct and simple and eficient in operation, all of which will morefully hereinafter appear.

In constructing ourimprovements,as shown in the drawings, we use anordinary supporting-frame A, having a door-opening a and provided with aframe B above the same. To sustain the frame in its dierent positions,we provide an inverted-U-shaped rock-shaft C, which has two dependingarms c, to which the frame is pivotcd by means of the brack- Serial No.711,248. (No model.)

ets C', that are secured to the door by means of ordinary wood-screws.From this construction it will be seen that the transom is swung outfrom its closed position, as shown in Figs. 3 and 4, and that the heel cof the transom bears against the supporting-frame, as shown in Figs. 3and 4. AIn this way the frame can be made to open inwardlyinto thestore-room entirely, and thus avoid the catching of the dirt and rainfrom the outside, and at the same time the weight of the heavy transomis divided between the rock-shaft and the frame, thus holding the frameat several points and more securely than when it is merely held upon twopivots, while at the same time the transom is much more readily insertedinto position or removed therefrom whenever occasion requires ornecessity demands.

To lift the transom and hold it in its various positions, we provide alifting-rod D, which is connected with a lever-arm E, that is pivotallyconnected to one of the depending arms of the rocker-shaft by means ofthe link G and the C-shaped clip g. As thelifting-rod is raised (se'eFig. 3) the connectinglink tends to assume a horizontal position, whichaction forces the depending arms of the rocker-shaft outwardly, therebycarrying the transom on its pivot outwardly, and as the superior weightof the transom is above the pivotal points the transom also tends toassume a horizontal position; but the heel of the transom bearingagainst the door-frame holds it at an angle until it .is entirelyraised, thus opening the same gradually to one side of the frame. Abracket l-I is provided and secured to the door-frame, through which thelifting-rod is passed. This bracket is provided with a thumb-screw h,adapted to press against the lifting-rod, and thereby hold it in anydesired position and also hold the transom in such position.

It is desirable to provide stop mechanism which will limit the upwardmovement of the transom and at the same time take part of the weight ofthe transom, and in order to accomplish this result we prefer to providea U-shaped stop-rod I and drive it into the door-frame, as shown inFigs. l and 4. The transom is provided with a stop-lug K, that isadapted to bear against the upper portion IOC) of the stop-rod when thetransom reaches its most open position, which is substantially ahorizontal plane. The C-shaped clip on the lifting-rod is also arrangedto contact a bracket H on the door-frame, and the transom has a secondstop-lug K', which has its free end projecting through the openingformed by the C-shaped clip, as shown in Fig. 3, so that when thetransom is in its most open position these stop-lugs rest again st theirrespective stops and take a portion of the weight from the pivots.

The lever-arm E, as above stated, is pivotally connected to one of thedepending arms of the rock-shaft and has a projecting portion e, adaptedto rest against such depending arm, as shown in Fig. 2, when the partsare in their closed position.

A projecting lug d' is formed on the liftingrod and adapted to bearagainst the free end of the stop-lug K when the parts are in their openposition and during the initial downward movement of the lifting-rod.This projection lug forces the lower end of the transom downwardly, andthus assists in the closing operation.

XVe claiml. In an apparatus ofthe class described ,the combination ofaloosely-mounted transom, a rocker-shaft provided with a depending-armmechanism pivotally secured to the transom to sustain all of the Weightof the transom, and mechanism for moving the depending arms of therocker-shaft outwardly and inwardly to open and close the transom,substantially as described.

2. In an apparatus of the class described, the combination of a U-shapedrocker-shaft adapted to be secured to a frame above the transom so thatits arms depend therefrom, a transom pivotally connected to thedepending arms of the rocker-shaft, a lifting-rod, a link mechanismconnecting the lifting-rod with the depending arms of the rocker-shaftto move the same and open and close the transom, substantially asdescribed.

3. In an apparatus of the class described, the combination of a U-shapedrocker-shaft arranged to be pivotally secured to a frame or similarportion above the transom so that its arms depend therefrom, a transompivotally connected With the depending arms of the rocker-shaft, avertically-movable liftingrod, a lever-arm pivotally con neeted to oneof the depending arms of the rocker-shaft, a link connecting thelever-arm with the lifting-rod and stop mechanism for limiting theupward the combination of a U-shaped rocker-shaft arranged to be securedto a frame or similar portion above a transom so that its arms dependtherefrom, a transom pivotally connected with the depending arms on therockershaft, a lever-arm pivotally connected with one of the dependingarms, a C-shaped clip on the lifting-rod, a link pivotally connectingthe lever-arm of the rocker-shaft with the C- shaped clip, a stop-lug onthe'inner end of the transom passed through the opening formed by theC-shaped clip, and stop mechanism on the frame portion to assist inlimiting the upward movement of the vertical rod and transom,substantially as described.
